patch 8.2.0867: using {xxx} for encoding a modifier is not nice Commit: https://github.com/vim/vim/commit/fccd93f0917234b962ce07d1df3adf9d7105936f Author: Bram Moolenaar <Bram@vim.org> Date: Sun May 31 22:06:51 2020 +0200 patch 8.2.0867: using \{xxx} for encoding a modifier is not nice Problem: Using \{xxx} for encoding a modifier is not nice. Solution: Use \<*xxx> instead, since it's the same as \<xxx> but producing a different code.

" Test feedkeys() function.

func Test_feedkeys_x_with_empty_string()
  new
  call feedkeys("ifoo\<Esc>")
  call assert_equal('', getline('.'))
  call feedkeys('', 'x')
  call assert_equal('foo', getline('.'))

  " check it goes back to normal mode immediately.
  call feedkeys('i', 'x')
  call assert_equal('foo', getline('.'))
  quit!
